A system for powering various rotating vehicle accessories such as an alternator, a power steering pump, and an air-conditioning compressor from both a water pump and an engine's crankshaft. At relatively low engine crankshaft speeds, the accessories are driven by a clutch mounted on a water pump at a first speed ratio relative to the engine crankshaft speed; at relatively high engine crankshaft speeds, the accessories are driven by the crankshaft at a second speed ratio relative to the engine crankshaft speed.
